Goldman Sachs Group Inc (GS) raised more than $7 billion to invest in a fund that purchases secondhand stakes in private equity, $2 billion more than its original goal for the fund raise, Reuters reported.

The fund is called Vintage VII and focuses on buyout and distressed strategies in developed markets. It's run out of Goldman's asset management division.

Secondaries allow investors cash exposure in different markets without much concentrated risk. They also may have quicker profit returns because they often invest in more mature funds.

Beware Tesla fanboys: Tesla (TSLA) burning money, but shareholders are the likely ones to blister and feel the pain. The standard 90-day corporate equity lockup period for Tesla, following its $402.5 million stock sale of March 16, ends Thursday TheStreetreports. As a result, Tesla will be free to conduct another stock offering as soon as Thursday, which is a real possibility given the electric car company's debt situation, partly due to its Solar City investment, and need for additional cash. Any new issuance the company may seek would likely need to take place before July, which is when Tesla issues its quarterly report on car sales. Alternatively, an offering could come in late August after Tesla issues its quarterly financial report.

Amazon eyes a new prize: Amazon (AMZN) may be preparing a deal to buy Slack Technologies in a deal that could value the messaging startup group at more than $9 billion, TheStreetpoints out. With Microsoft's (MSFT) deal for LinkedIn being well-received, this deal seems logical for an Amazon that is aggressively expanding into the cloud.

One has to wonder though: why isn't Apple (AAPL) considering Slack or for that matter, Twitter (TWTR) . Each service would provide valuable insight into human behavior from which to build new products and services.
